How much are a self-employed dentist's social security contributions?

As for anyone self-employed as a main occupation: 20.5% of net income up to €75,024.54, then 14.16% up to €110,562.42, plus the fund's management fees. The minimum is about €925.59 per quarter, and the maximum contribution €5,304.62, fees included.

How much is a dentist's NIHDI social status in 2026?

The 2025 allowance, paid in October 2026, amounts to €3,860.98. The 2026-2027 dentists-mutualities agreement raises the 2026 allowance, paid in 2027, to €4,592.21, thanks to the abolition of the telematics allowance. The amount is indexed every year. It requires having signed up to the agreement for the whole year and reaching the activity threshold.

Where does the NIHDI social status money go?

Never into the dentist's account. The NIHDI pays it to the insurer or pension provider with which they have taken out replacement income insurance in case of invalidity, a pension contract, or both. The contract must be taken out by 31 December of the allowance year; the social PLCI is the most common option.

Does a dentist have to charge VAT?

No for care with a therapeutic purpose, which is exempt under Article 44 of the VAT Code. Yes for procedures with no therapeutic purpose, such as purely cosmetic whitening. The flip side of the exemption: VAT paid on equipment, supplies and work on the practice cannot be recovered and must be built into the cost of setting up.

Social or ordinary PLCI for a dentist?

The social PLCI, in most cases. Its 2026 ceiling is €4,701.54 compared with €4,086.34 for the ordinary one, and part of the premium funds incapacity, invalidity and death cover. For a practitioner whose entire income depends on their hands, this solidarity element has real value.

When does it make sense for a dentist to move to an SRL?

When profit consistently exceeds what the household spends. An SRL lets you leave the surplus in the company, taxed at 20% on the first bracket, and fund an EIP. It adds double-entry bookkeeping and a minimum director's remuneration. The exact threshold depends on your situation: have it costed.

Is a self-employed dentist covered in case of illness?

Yes, by the NIHDI, from the first day if the incapacity lasts at least 8 days. But the benefit is a flat rate: about €2,148.64 a month with dependants, whatever the income. Private income protection insurance fills the gap, and overheads cover can pay the practice rent and salaries.

The first year: what lies ahead for a Dentist

Worked example

Take Youssef, 31, who opens his practice in Namur

Take Youssef, 31, a methodical dentist who leaves his salaried job in September to take over a practice in Namur. His partner, Leïla, will run reception and the diary as an assisting spouse. First shock: the VAT on the new chair and the intraoral scanner. He had budgeted for it as recoverable; since his treatments are exempt, the 21% stays at his expense.

On the INASTI side, the good news comes quickly. As a first-time starter, he pays about €477.98 per quarter. Methodical as he is, he still opens a separate account and puts 20.5% of each month's net takings into it: he knows the adjustment will come two to three years later, on his real income.

In December, his accountant asks him a question he was not expecting: has he signed the contract that will receive his NIHDI social status? Without a contract taken out before 31 December, the year's allowance is lost. He signs a social PLCI on the 19th.

In the spring, their daughter is born. Youssef discovers birth leave for the self-employed: up to 20 paid days at €107.14 gross per day. He takes ten, closing the practice for a week. What worries him most, in the end: his income protection insurance, which he still has not taken out.

INASTI status and contributions: what a self-employed dentist pays

A dentist working in private practice is self-employed as a main occupation. They join a social insurance fund and pay quarterly contributions: 20.5% of net income up to €75,024.54, with a minimum of about €925.59 per quarter, management fees included.

At the start, these contributions are provisional: in the absence of a known income, the fund calculates them on a minimum income of €17,374.08. A dentist joining for the first time also benefits from "first-time starter" status, which brings the bill for the first four quarters down to about €477.98.

The trap is well known, but it hits dentists particularly hard: a patient list fills up fast, and actual income often exceeds the minimum from the first full year. INASTI adjusts (regularises) the contributions 2 to 3 years later, on the income actually earned. The mechanism is explained in how social security contributions are calculated and in the article on the first-year trap.

A rate of 14.16% between €75,024.54 and €110,562.42 of net income, and nothing above that.
The fund's management fees: 3.05% to 4.25% of contributions, depending on the fund.
A spouse or partner who helps at the practice (reception, diary, invoicing) comes under assisting spouse status, with their own contributions on a minimum income of €7,632.44 under the maxi-status.

NIHDI social status and the agreement: the benefit specific to dentists

The NIHDI social status is an annual sum that INAMI (the NIHDI) pays to dentists who sign up to the national dentists-mutualities agreement and keep to its fees. It amounts to €3,860.98 for the 2025 allowance and €4,592.21 for the 2026 allowance. It never lands in the current account: the NIHDI pays it to an insurer or a pension provider.

The contract that receives it must be an insurance policy guaranteeing a replacement income in the event of invalidity, a pension contract, or both. It must be taken out by 31 December of the year to which the allowance relates. In practice, many dentists link it to a social PLCI, which combines both elements.

Three further conditions apply: having signed up to the agreement for the whole allowance year, holding accreditation as a general or specialist dentist (or an approved training plan), and reaching the activity threshold of 300 services recorded with health insurance. The threshold does not apply to a dentist accredited for less than five years.

In the year the dentist receives their first NIHDI number, the allowance is calculated pro rata to the full months of membership. Payment is made the following year: the 2025 allowance was decided and paid in October 2026, on an exceptionally delayed timetable. So expect a one-year gap between the year worked and the money being invested.

Pension: social PLCI first, EIP if the practice becomes a company

The statutory pension of a self-employed person remains modest, and dentists, whose income quickly exceeds the calculation ceiling, feel this more keenly than others. The first layer to fill is the social PLCI (free supplementary pension for the self-employed, VAPZ in Dutch): up to 9.4% of reference income, with a ceiling of €4,701.54 in 2026, deductible as a business expense.

The social PLCI costs a little more than the ordinary PLCI (ceiling €4,086.34), but part of the premium funds a solidarity element: incapacity, invalidity, death. For a profession that relies entirely on your hands and back, this element is no detail. The PLCI simulator works out the net cost after tax.

If the practice becomes a company, an individual pension commitment (EIP) becomes possible. The company pays the premium, deductible from corporate income tax, within the limit of the 80% rule. The PLCI stays outside this rule: the two can be combined.

Protection: income protection and professional liability insurance

A dentist who can no longer treat patients invoices nothing, while the practice rent, the chair lease and the assistant's salary keep running. The NIHDI pays a flat-rate benefit, the same whatever the income: about €2,148.64 a month with dependants, €1,704.56 for a single person.

The NIHDI benefit is due from the first day, provided the incapacity lasts at least 8 days. For a busy practice, the gap with actual income is considerable. Income protection insurance fills it, up to about 80% of professional income with most insurers.

On the liability side, one wrong move can quickly prove costly: professional liability insurance is essential. Usual ceilings range from €1,250,000 to €2,500,000 per claim; check that they cover implantology and cosmetic procedures if you carry them out.

Income protection: reread the exclusions affecting the back, shoulders, hands and mental health conditions, frequent causes of time off among practitioners.
Choose a waiting period that your cash flow can handle: a month of fixed costs with no income needs preparing for.
Overheads: some insurers offer cover that pays the practice rent and salaries while you are off work.

Tax, VAT and companies: what is specific to a dental practice

Dental care for therapeutic purposes is exempt from VAT (Article 44 of the VAT Code). Dentists therefore do not charge VAT to their patients, but nor can they recover the VAT they pay: on a chair, a panoramic X-ray or an intraoral scanner, the 21% remains a cost.

Procedures with no therapeutic purpose, such as purely cosmetic whitening, fall outside the exemption and are subject to VAT. A dentist who carries them out regularly must register for VAT for that part of their activity. The line is drawn procedure by procedure: have it checked early. The regime is explained on the VAT for the self-employed page.

Equipment is depreciated over several years, and a practice's actual expenses far exceed the flat-rate allowance for the liberal professions, capped at €5,340. Claiming actual expenses is the only realistic option: it calls for rigorous bookkeeping from the first month.

Moving to an SRL/BV (private limited company) becomes a question when profit consistently exceeds what the household needs. The company pays 20% tax on its first €100,000 of profit if it pays a director at least €50,000 gross, a requirement waived for the first 4 financial years. For a costed comparison, you can ask to be contacted by a licensed professional.

Worked example

Two routes for the same practice

Picture a dentist who has been established for five years, whose profit has settled well above what the household spends. First route: they stay a natural person. All their profit is subject to personal income tax, in the highest brackets, and their social security contributions follow it up to the ceiling of €110,562.42. Simple, low accounting costs, but no room to save other than through the PLCI.

Second route: they set up an SRL, pay themselves a remuneration that covers their lifestyle and leave the rest in the company, taxed at 20% on the first bracket. The company can fund an EIP and buy the equipment. In return: double-entry bookkeeping, annual accounts to file and a minimum remuneration to respect after the start-up period. The right choice depends on the actual surplus, not on turnover.

Mistakes we often see

Budgeting the VAT on equipment as recoverable: since therapeutic care is exempt, it adds to the price of the chair and the equipment.
Forgetting to take out the pension or invalidity contract before 31 December: without it, the year's NIHDI social status cannot be paid.
Leaving the agreement to set your own fees without costing the loss of the social status over your whole career.
Taking out an ordinary PLCI instead of a social PLCI, and being left without incapacity cover in a profession that relies on your hands and back.
Invoicing purely cosmetic procedures under the VAT exemption, when they are excluded from it.
Spending the cash of the early years without setting aside money for the adjustment of social security contributions.
